Benj,
save yourself the pain of watching this movie just to satisfy your curiousity. It is really awful. If you need more convincing then check out a response I wrote to Film Threat's positive review back in November:
Redacted is the worst movie De Palma has ever made, which is weird because he's made it before (Casualties Of War). The video diary technique doesn't just seem inauthentic, but as more amatuerish than Blair Witch 2 Book of Shadows. The plot is trite and devoid of genuine emotion. The most sickening scene is where the beheading of a US Army soldier is shown in gorey detail, and it is presented as though the soldier deserved it since he participated in the key rape scene. It distorts the incident it was loosely based on completely. The film portrays the jihadis in Iraq as native freedom fighters avenging their countrymen, which couldn't be farther from the reality of Iraqi Alqaeda's genocidal foreign arab terrorists and the ethnic sectarian insurgents who have ruthlessly slaughtered their fellow iraqis by the tens of thousands in the past 4 years. The two US army soldiers that are the movie's bad guys are hollywood caricatures of racist redneck neanderthals, like d-list equivalents of the klansmen in A Time to Kill. They do things that wouldn't really be permitted in the military today, like hang up confederate flags and casually use phrases like "sand n*gger", even around black soldiers. The fat one is called Rush (like RWer Limbaugh), and the stoner Flake. The real Flake was a complete sociopath who was discharged for his psychosis, but this Flake is presented as a generic soldier. The sensitive intellectual in the platoon is called Blix (like Hans Blix, how subtle), the "dead meat" character is called Angel, and the one who will eventually report the rape/murder to the authorities is named Lawyer. Flake falls asleep at the checkpoint and then opens fire on a car that tries to bolt through the checkpoint. Predictably, the car is not a suicide bomber but carrying a pregnant woman. In one of the endless contrived scenes another soldier asks Flake if he feels remorseful and he says shooting hajis is like stomping cockroaches. This after he had been giving away his food to iraqi children in the opening scenes. When an IED is placed near the checkpoint later it is presented as vengeance for the pregnant woman. The IED kills the Danny Glover-esque veteran sargeant. He basically says he's getting too old for this shit just before being atomized by an IED hidden in an armchair he falls into. Seriously, he stumbles and falls into a chair which then explodes just the insurgents planned somehow. Shortly afterward Rush and Flake hatch a plan to rape an attractive local young Iraqi woman whom Rush has groped during her trips through their checkpoint. The rape doesn't seem to be motivated by payback for their dead Sarge so much as Flake and Rush are simply drunk, "horny" and want to "get some". Inexplicably the rest of the squad only whine passively in response. Even the squad's corporal just freezes and then runs outside after Flake sticks a pistol in his face, even though he's holding an M16 the whole time. A third squad member, Salazar, participates in the rape for no apparent reason other than he wants to video it because it's his "ticket to film school". When the rape happens DePalma can't resist altering the real incident (in which a 14 year old girl was raped) to a more salacious one, in which a buxom young iraqi woman has her breasts fondled through her nightshirt by a drooling Rush before being raped while the camera held by one of the rapists does a close-up on her face. It's I Spit on Your Grave repackaged as a political diatribe. Next we see an interview with the tearful father of the murdered iraqi family and he promises that he will get justice without waiting for the US to investigate. So when Salazar is kidnapped and beheaded on video we are supposed to view this as karmic justice. It is repellent and pointless except to provide another sick thrill for Redacted's target audience, people who consider US servicemen as fascist thugs. In real life two US soldiers were abducted and brutally tortured and beheaded, but this was done by Iraqi Alqaeda probably to retaliate for its leader Zarqawi being killed by US forces 9 days prior to the kidnapping. The beheadings were carried out by Zarqawi's successor. After the rape/murder investigation became news Iraqi Alqaeda released a second video spinning the rape/murder as the motivation for the previous months' beheadings but no mention had been made of that when they claimed responsibility then. So the beheadings would have happened regardless of whether the rape/murder incident had ever occurred. Depalma glosses over that, ignoring the very existence of Zarqawi and Iraqi Alqaeda. Instead the implication is that the beheadings are just eye for an eye cycle of violence that the racist american thugs initiated. All this makes Redacted sound like it has a lot of action, but really 90% of it is boring as hell. Nothing whatsoever happens in the first 20 minutes. Redacted's final 20 minutes following the beheading are just filler to stretch its length to 84 minutes. In the beginning we watch Lawyer absent-mindedly crunching and uncrunching a plastic water bottle for half a minute and a drop of sweat run down Rush's face for a quarter minute. After Salazar's beheading we sit through Rush and Flake just bullshitting about nothing for seven minutes straight. Then the movie wanders through Lawyer trying to convince military authorities that an atrocity happened while they try to cover it up. Reality is again completely different in that in 2006 when a soldier reported the incident the military moved swiftly to investigate and prosecute the crime. The real Flake is facing the death penalty and his accomplices were given life sentences. Redacted is plotless propaganda that is hollow to it's core and plays loose with the truth. Just before the credits roll the audience is subjected to a montage of a couple minutes of actual photos of Iraqi corpses and bloody children. No context is given for the photos, but most of the bloody scenes seem to depict the aftermath of car bombings (although one assumes DePalma wants the audience to think they were victims of american attacks). But although the audience is told that these are real photos, the final one (of the rape victim character Farah) is actually staged, using the Farah actress posed to look horrifying. In the real incident Abeer Hamza was the girl who was raped, but DePalma is so focused on demonizing american servicemen as cartoonish racist garbage that he forgets to pay any attention to her, except as an object.

LoudMouth! It's been so long. Welcome back.

There are probably many reasons why this movie just now made it to Austin, but most likely the main reason is that it only had a 15 screen limited release. I reckon Magnolia pictures didn't want to make a billion prints of this thing, as they knew that they were going to take a bath with what they had already invested and probably weren't willing to open themselves up to any more liability (hence the editing of the final montage of "real photos").

The Dobie is a Landmark theater, but it probably wouldn't have been worth it for them to promote and screen; they definitely don't have the media voice and backing that the Alamo does, even though watching it in the Egyptian tomb room would have been more appropriate.

All that to say that the official release date was back in November, which is why it has been available On Demand for awhile.
